    Default Variation on a theme...

    I made a (very) small chisel from a piece of HSS a couple of years ago. It's a handy little thing & has seen quite a bit of use. The blade was cut out of a thin piece of hard HSS, and has only a small bolster, & it has little to stop it being driven into the handle. This chisel never needs other than a light tap, but I would like to have used a tapered ferrule, to give a more positive register. Recently, I was making a chisel handle for a friend, to take a tapered ferrule, so I decided to take on the challenge & try making a couple for myself.

    Turning the outside taper is very straightforward, but I don't have a boring bar small enough for the inside taper. So, being a long-time wood turner, I just hand-turned the inner taper with a scraper, after drilling it out to the minimum diameter. Brass is pretty easy stuff to work with, & by the time I'd done a couple, I was in the swing of it, so I made two for myself.

    Now I have 3/32" and 1/16" mini-chisels: Mini chisels.jpg


    The only downside is that such narrow chisels are a beast to sharpen freehand!
    Cheers,

    They look fantastic Ian.
    What timber did u use for the handles ?
    Sharping would be difficult as u pointed out .
    But then ,when u need a chisel that size, I can see were they would be just the ticked .
    Has regard to sharping ,I think they would be the size when I would get out my long forgotten guide.

    One of my favourites, She-oak. (But She-oak that's workable, not splintery iron like the stuff we had at the w'shop! )

    I gave mine away years ago, so haven't any choice but to freehand them. They are ok if I tackle them on a good day, & take them very carefully. Fortunately, being an infrequently-used tool, they need infrequent sharpening...

    Great looking chisels Ian.

    I have cut short small tapers on soft metals like brass and ally using a broken HSS drill bit ground into a tapered half circle cross section.
    I place the bit in a chuck and then run the bit slowly into a pre-drilled small hole in the ferule that is the smallest hole in the taper.

    Bob - is the drill ground to the size of the finished (internal) taper so it acts like a reamer?? I didn't think to taper the tool & use it in the tailstock chuck, but it would probably be much easier to manage than what I did. I will give something like that a go, next time. Hand-holding the scraper was ok, but hard to keep the internal wall straight - both got slight curve to them, which I allowed for by dishing the taper on the handle slightly..
